Replacement test tubes

[torface]

My cat decided that he likes to play with my API test tubes and now I only have 1 left :(

I have an API test kit and ive think ive seen replacement tubes for them, but I was wondering if there are any alternatives (preferably non glass) that still show the correct water line? I think someone mentioned before that the Sera test tubes are good? Can someone point me in the right direction please?

I actually have just seen some plastic centrifuge test tubes with lids and volume marks on the side on flebay. Think these would work?

Theyre made of Polypropylene...

I would think they would be OK as the test liquid is in plastic containers so must be non reactive:encouragement:

[torface]

Thanks Ineke, theyre fairly cheap so would be ideal :)

I use ones similar in the field and they are AOK.

I guess anything would work as long as you fill it with the same amount of water as in the original tubes, although, the colour might change a bit due to different density if the new tubes are thicker :encouragement:

Cats are stupid eh? Lol

13 to go.

Not stupid ninja, just mischievous!

Those ones are only $7 for 12 so I'll give them a go, if they don't work I'll try something else. I'm pretty sure the api tubes have a line you fill up to which is 5ml, these are 10ml but seem to have increments up the side. :encouragement:

I totally agree, only thing I was concerned about is if the are much wider & therefore looking through more of the test solution then the visible colour would be a little darker giving you a slightly false reading :victorious:

[torface]

Oh I see... Hmmm well the bloody colours are so hard to tell anyway lol

[Squiggle]

Hahaha, fair point! :victorious:

You can use a syringe to measure into any size container as well, doesn't really matter. Some of the tests, i.e the easy to tell colour change ones, you can even use a syringe and measure out 1ml rather than 5, then you can use 1/5th of the drops from the reagent. Don't ever use it for something vital (i.e shrimp dieing ammonia suspected), but it makes rough testing for nitrates or even cycle testing easy. My house looks like a junkies, have syringes all over the house that ocasionally get deposited elsewhere when i get distracted from testing.

Looks rather opaque, a clear plastic tubing maybe easier to judge the colour/shade ?

Thanks. I was hoping to get some plastic ones though so they don't get broken again...

I might just wait till I have to get some other stuff because it makes them so expensive with shipping :/

[Squiggle]
